An 18-month-old male child presented with right eye white reflex for about 2 months. On fundoscopy, the patient was noted to have right eye retinoblastoma. In addition, there was posterior lens capsular opacity [Figure 1]a with a prominent posterior tunica vasculosa lentis (PTVL) dipping into the tumour located at the optic nerve head, confirmed on ultrasound B scan [[Figure 1]a, inset]. After 3 cycles of systemic chemotherapy, the tumour shrinkage resulted in posterior traction by the vasculature causing radial capsular folds [Figure 1]b. PTVL normally starts regressing in the second trimester. In this case, the continued blood supply from these primitive vessels to the retinoblastoma possibly inhibited the regular vascular endothelial growth factor (VEGF)-induced angiogenic mechanisms that take place during vascular regression, leading to persistent fetal vasculature.
